Millennium Marine B100 ComfortMax Mid-Back Folding Boat Seat — White, 400 lb Capacity, Weather-Resistant

The Millennium Marine B100 ComfortMax is a mid-back, folding boat seat built for long-term weather resistance, supportive comfort, and universal mounting on most pedestals.

Designed for anglers and recreational boaters who need reliable seating that stands up to sun, spray, and repeated use, the B100 blends a lightweight frame with breathable, water-shedding materials. The seat’s ComfortMax contouring reduces pressure points during long days on the water while mesh-like-coated fabric prevents dew, holds no standing water, and speeds drying after rain. Constructed on a powder-coated aluminum frame, it supports up to 400 pounds while folding flat to clear sightlines or free up deck space.

How does this seat handle wet, salty, or variable weather conditions?

The B100 uses a specialized ultra-cool coated fabric that resists water absorption and natural breakdown, plus a breathable design that lets water drain quickly. The coated mesh won’t retain dew, and the rapid-dry surface minimizes mildew and odors.

• Weather-resistant coating repels rain and spray
• Mesh-like construction enables fast drainage
• Materials selected to resist UV and salt exposure
• Powder-coated aluminum frame resists corrosion

Will the seat fit my boat and mounting system?

The B100 is engineered for broad compatibility: it mounts to most standard boat seat pedestals and swivel plates. Its folding mechanism also reduces height when not in use, making it easier to adapt to tight cockpits or switch between seating and open-deck configurations.

• Compatible with standard pedestals and swivel plates
• Folds flat to improve visibility and free deck space
• Lightweight 7 lb design simplifies installation
• Solid 400 lb weight capacity for stable support

How comfortable and supportive is the ComfortMax design?

The ComfortMax profile is contoured to support both sitting and leaning postures common in fishing and cruising. The breathable, ultra-cool fabric reduces heat buildup and the shape helps distribute weight to reduce fatigue during all-day outings.

• Contoured mid-back design supports posture and casts
• Ultra-cool coated fabric keeps the surface cooler in sun
• Breathable construction reduces sweat and discomfort
• Lightweight cushioning delivers comfort without exposed foam

What are the key specifications and build details?

The B100 balances durability and low weight with practical dimensions for most boats. The strong aluminum frame is powder coated for corrosion resistance, and the overall package is sized to fit common cockpit layouts while supporting heavier users.

• Weight capacity: 400 pounds; unit weight: 7 pounds
• Powder-coated aluminum frame for strength and weather resistance
